WHITING ARNOLD, OF MANDARIN, FLORIDA.

BOAT-PROPELLING DEVICE.

Specification of Letters Patent.

Patented Nov. 12, 1907'.

Application Sled July 31| 1907. Serial No. 386,344.

To all lwhom it may concern:

Be it known that I, WHITING ARNOLD, a citizen of the United States, and a resident of Mandarin, in the county of Duval and State of Florida, have invented certain new and useful Improvements in a Boat-Propelling Device, of which the following is a specification.

The object oi my invention is to provide a new and improved boat propelling device, which is simple in construction, permits of driving the vessel at high speed without requiring comparatively great power, dispenses with a long shaft connection between the motor and the propelling device, thus avoiding thrust friction and whereby the paddle at all times works in dense and undisturbed water, thus causing greater speed.

In the accompanying drawings, in which like letters oi reference indicate like parts in all the figures:- Figure l is a vertical side view of my4 improved boat or propelling device mounted on a vessel, parts of which are broken away. Fig. 2 is an elevation of my improved propelling device.

A shaft l is mounted in suitable bearings 2 permanently secured and bolted on the vessel and this shaft is connected with a sprocket wheel 3 which is rotated in the direction indicated by the arrow from a motor, such asia steam engine, and the like, or' in fact this shaft can be rotated from the motor in any other suitable manner as the method and means of rotating the shaft l form no part ofmy present invention. The shaft l is provided. with a crank 4, the cross piece of which passes loosely through lugs 5 projecting from a sleeve 6 bolted to a hollow or solid bar 7 which passes through I said sleeve and to the lower end of which bar a paddle `8 is secured` which extends transversely to the length of the boat and may be oi any desired or suitable construction or size. The upper end oi the bar 7 is pivotally connected with the upper end of stay rods 9 pivoted at theirlower ends to suitable bearings l0 secured on the deck oi the vessel 1l. The bar 7 of the paddle projects through a suitable well l2 in the hull of the boat.

The operation is as ollows:-The shaft l is rotated in the direction of the arrow shown in Fig. l whereby,

the crank 4 is moved to the right and downward. This first swings the paddle 8 in the direction to the right and at the same time the paddle is gradually moved downward and as the crank passes in the said direction down beyond the horizontal through the plane ol' the shaft 1, the bar 7 and paddle 8 continue their downward motion but at the same time are moved in the direction toward the stern of the boat and as by this time the paddle is fully .immersed its great power pushes the boat forward in substantially the same manner as a boat is propelled by means of an oar. It will be observed that as the crank shalt swings downward toward the right, the bar 7 passes into the opening between the-two sides of the crank as otherwise the movements of the bar 7 could not take place and as the crank approaches the vertical position and extending downward the bar 7 is gradually moved out from between the two arms of the crank. As the shaft l completes its rotation the crank arms move upward to the left thereby lifting the bar 7 into its highest position and so that the paddle in rising offers as little resistance -or back pressure as possible.

Having described my invention what I claim as new and desire to secure by Letters Patent is:-

1. 'lhe combination with a floating vessel, of a driving shaft provided with a crank, means for rotating said shaft, a har pivotally connected with the crank, a paddle on the lower end oi' said bar, and a stay rod pivoted at its lower end to the vessel and at its upper end to the upper end of the bar carrying the paddle, substantially as set forth.

2. 'lhe combination with a vessel, of a driven shaft having a crank with two arms, means for rotating said shaft, a sleeve mounted pivotally on the crank between the arms, a har passing through said sleeve and secured thereon, a paddle on the lower end of the bar and a stay rod pivoted to the upper end Vof the paddle carrying bar and to the vessel, substantially as set forth.

Signed at Jacksonville in the county of Duval and State of Florida this 15th day of June A. D. 1907.

WHITING ARNOLD.
